Question Mi Band 3 black screen

My Mi band 3 screen suddenly turns black after I left it unused for 4 days. I've tried to flash the band with custom firmware, but the problem persist. Apart from that, the touch screen (its still vibrated when I activate swipe to unlock), connection, and vibration (find band and notifications makes the band vibrate) still ok. Any ideas how to deal with this?

If uploading the firmware does not help, return the bracelet to your dealer under warranty.

He won't be able to claim it because he had installed custom firmware...

Even if the display is black, the original firmware can be downloaded. Vibration and pairing is functional.
